The Celtic boss said: “Strengthening the squad is very important. We need players we know we can rely on in certain situations. It is hard to put a number on how many we need. It also depends on what is available. My trip to Birmingham [to watch Kozak] went okay. We have a lot of scouts so we will make it right come the end.”
Deila sounds as if he is planning to make moves for players in January, but he has confirmed he does not have a number of signings he wants to bring to Parkhead.
He is also restricted by what players are available, and which clubs will want to sell in the January transfer window.
However, he has confirmed he travelled to Birmingham on Monday, to watch Aston Villa take on Derby County in an Under-21 fixture.
BBC Sport reported earlier this week that Deila was present to watch the tie, and he would have seen striker Libor Kozak score twice in an all action display, and lead his team to a 2-1 victory over Derby County.
Kozak rejected the chance of joining Celtic over the summer transfer window, as reported by the Scottish Sun, and clearly Deila believes the powerful Czech forward will be more open to a move in January.
However, upfront is not the only position which needs improving in the Bhoys squad, and Deila is sure to sanction various other moves in January.
